Abstract (2. Language):
Since the amount of accidents on suburban roads is higher compared to urban roads due to vehicle speeds and topography, local and long communication paths, it is essential to examine and study the roads safety at the design stage of a new route and also the development and maintenance of the current roads through improvement and elimination of accident black spots. The study is conducted based on descriptive analytic method. Descriptive and inferential statistics were used for statistical analysis of collected data. Inferential statistics such as Friedman test and mean analysis were used for data collected from field surveys and questionnaires and t-test was used to test the hypothesis significance and the reliability of questions was tested using Cronbach's alpha. Following, human factors were in second place among them, speed and unauthorized overtaking, deviation to the left and undue haste acceleration were among the human reason for the accidents at the axis, explaining that that two factors of speed and unauthorized overtaking were among the affective factors for accidents at the axis regardless of the categories. Technical factors and quality of the car s were at the third place and finally natural environment were at the fourth place. Furthermore, hypotheses relating to the factors with accidents axis mentioned above were proven except the environment factors, the significance of which were not approved.
